To all whom it 7m1. 1..-mu:ern;

do itltnown that l, J ENS JACOBSEN, acitizen of Germany, residin at Ferndale, in the county of Humboldt andState of California, for more than one year last past, have invented a new and useful Wrappin -Machine, of which the following is a specification.

This invention relates to packaging ma chines, and has for its principal object to provide a machine for wrapping cubes of butter tomatic throughout, and being arranged to receive the articles and inclose the same in sheets of paper, cloth or other material. 7

A further object of the invention is to construct a machine of this type in which the separatecubes or articles are fed onehy one into the wrapping'mechanism, a sheet ofwrapping material of appropriate'size being automatically cut from a rol or sheet and is with the article, and the inclosin sheet being first folded around .the sides of the article,

after which the ends are folded or tucked,

and the completely wrapped article delivered from the machine.

A still further object of the invention is to provide a wrappin machine in which the article to be wrapped serves as the initial operating member c uring the wrapping operation, and in which said article serves, also, as a means for automaticall feeding the wrapper to' )osition in the machine.

A still further object of the invention is to provide a wrapping machine in which a portion'of the wrapper folding mechanism serves to retain the article iii-position until the discharge point is reached.

A still further object of'the invention is to provide an end folding mechanism, which, urin 8. single reciprocatory movement, will fold t e ends of the wrapper projecting beond the ends of the article. I

A still furtherobject of the invention is to provide a simple form. of folding-device which ina be reciprocated past the rejecting unfoldhd end of a wrap or, and i tiring" asi le' movement will comp etel 'v fold-the four si es of said wrapper.

I .A still further object of the invention is to provide a machine especially adapted for acltaging butter. and wherein a mass of bu ter may be supplied to the machine and autos 7.0, the cubes being separately wrapped and folding ope-ration.

' delivered as separate articles,each of a given size, and of approximately the same weight.

-With these, and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arra ement of parts, hereinafter fully describilfi, illustrated in the accom )anying drawings, and particularly points out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may, be made without departing from'the spirit or sacrificing any of the adva'nta es 0 the invention.

Similar numerals of reference are cmployed to indicate corresponding parts '5 throughout the several figures of the rlranings.

The various working parts of the machine are supported on a suitable frmnework 20, which .may be formed of woodenbeams or in structural iron, and this frame comprises two main members that are arranged at a right T angle to each other, the general contour of the machine being in the form of the letter L. and both portions of the frame are .n-ovidml .4 with conveyors, the mass of butter being supplied to one of the conveyors and duringits transit to the second conveyor being out ilii-o the. form of cubes of approximately the same size, and approximately. the shine weight;

20 which are delivered one by one. by the sec- .1 -0nd conveyer,-to the packaging or wrapping mechanism.

{The shorter frame, shoyvn more clearly in Figs. 2 and 3, is provided with bearings for 2 5 the reception of a pair of parallel shafts 2].,

on which are mounted octagonal disks or drums 22 that serve as supports for an endless conveyor 23, that is formed of a plurality of pivotally connected slats, the upper-run of b the conveyer forming a movable platform on which the mass of butter is placed. Each end of each of the conveyer slats is provided with aprojecting pin 24 adapted to be engaged by the upper end of a pawl 25 that is 5 pivoted to a bracket 26'slida-bly mounted in ides 27 on ,the frame, and when the racketis moved in one direction, the conveyer will be advanced to an extent equalto the Width of a single slat, while on move- 4o ment in the opposite directionthe pawl will 1 turn onits pivot, in order. to pass. under the next succeeding pin. i

' The brackets 26 are coinlectedhy itman rods 28 to cranks 29, on a horizonta ly dis? 4 5 posed shaft 30 mounted in suitablesupportmg bearings carried by the frame, havin a timed operation in order to eflect aiorwars movement. of the mined intervals.

5o At-a point in advance of the delivery nd of the conveyor 23 is a second conveyor 32, that is. arranged at a'rightan is to the first corn veyer',, and is forms of a p urulity of pivotally connected slats 34. This conveyor is sup conveyor 23. at predeter- 5 5 portedby hexagonal disks or drums 35, su.p-'

ported bythe frame, and is operated in such mnnnerfas to receive in the present instance iive'ste i by step movements for each moveuncut o the conveyer 23. go In order to transfer the butter from the lcofiv eyer 23 to'the convo,

:tiori platform members 36' and 37 are em- .ployg g,theplatform-member 36 bein in the -.or1no iastri ,having i ts lower edge. veled in order that t "1232, a pair of stamay extend over thatportion.

oi the convoyer 23 which passes around the drum 22, and the butter is pushed by the mass on the convcycr over the strip 36 on to the strip 37, and from thence on to the conveyer 32, to be carried to' the packaging or wrapping mechanism, and during the movemcnt from the platlo'rn'i member 36 to the member 37, the mass of butter is cut into cubes oi predetermined size.

The cutting n'iechanism is disposed between the platform strips 36 and 37, and includes a frame. 39 having a plurality of guiding lugs 40 for the reception of a horizontally movable frame 4-1, that carries a plurality of Wire cutters 42. The wires 42ers arranged at cool-distant intervals, the spaces between them being equal'to the widths of the slats 34 of which the convcyer 32 is composed. The frame 41 remains stationary during each forward movement of the convcyer 23, so that the mass of butter will be' forced between the wires and will be provided with vertical cuts or incisions 'of a depth equal to the extent of forward movement ofthe conveyor 23. At the com )letion of this movement, the-frame 41 will moved endwise, or in 'a direction parallel with the direction in which the conveyer 32 moves in order to sever the mass laterally, and thus 'form a number of separate-blocks or cubes of butter. In order to operate the cutter frame, the shaft 30 is provided with a pair of disks 43, having cam grooves for the reception of antifriction rollers 44 carried by a vertically guided rod 45, the upper end of which is secured to one arm of a bell crank lever 46 that is pivoted-to the frame. The opposite arm of the bell crank lever is connected by a pi tman 47 to the lower portion of the framed}. The cams are. so timed that the frame 41 receives at each operation a movement in one direction t an extent equal to the distance betwee'neach two wires 47, after which the frame is stop ed .iintil the conveyor 23 has. again operate to .force. a second portion of the massof butter past the then stationary cutter wires 42, after which the frame 41 and cutter wires 42 are moved laterally to, the first position: It may here be,observed that. the mass ofbutter placed on the conveyor 23 is first shaped into the fbrm of.a large cube, the width of which is exactly equal to the combined widths of live, more or less, of the slats34.

The main frame of the machine is provided with supports for a horizontally disposed stationary shaft 50 on which a air of spaced disks 51 are revolubly mounted, and between these disks is a pair of spaced canrdisks 52 and'53 secured to the shaft, the disk 521m ring a cam groove 5'4,'and the disk 53 being provided with a cam groove 55.

blecured to the peripheries of the disks 51 are pockets or boxes 56 arran ed at cqui-distant intervals around the dis s', and of any desired number, live being alia es in the 4 extending plate 69 that is arranged at the despring pressed 73. This carrier is provided with laterally nes radiating from the axis of the shaft.

step by step movement, during which time pocket a slidably mounted carrier 70 is emsur ace ent-instance. These pockets or boxes are closed at the bottom, open at the top, and are rovided with side walls that are parallel with At the outer edge of each of the boxes is a laterally extending flange 57 having guiding grooves for the rece tion of folder plates 58 and 59, these plates eing arranged to act in successive order to fold the wrapper of paper, cloth or other material around the edges of the butter or other article to be wrap ed. The packages are received in these poo ets from the conveyer 32 in the manner hereinafter described, and the disks 51 receive a the wrapper is folded around the butter, this end of the wrapper being folded last, and the fully wrapped cube of butter is then discharged from the pocket, preferably on an endless conveyer arranged at the lower por- 'tion of the frame. In order to impart the step by step move ment, a pawl and ratchet mechanism of the construction shown in Fig. 4 is employed. This comprises merely a pawl carrying arm 61 pivoted on the shaft and having a pawl 62 arranged to engage with 1'. tchet teeth formed in a disk or wheel 63 that is loose o'r the shaft. At the rear of the fra1ne is-arranged a shaft 64 having a crank 65 that is connected by a pitman 66 to the pawl carrying arm 61. This shaft 64 is the main shaft of the machine and receives a single complete rotative movement for each cube of butter wrapped, and it requires asingle complete rotative movement of the shaft to'accomplish a single step movement of the ratchet disk 63. v

' The main frame is provided with inclined members 68, which support a transversely livery end of the conveyer 32 and is disposed at an'angle of about thirty-six degrees from the horizontal, this plate serving to receive the cubes of butter as .the conveyer passes over the adjacent hexagonal drum 3 5. 1

During the operation of the machine, one of the pockets or boxes 56 is stopped at each step'o the operation, at a receiving point immediately 1n advance of the, plate 69, as will be observed on reference to Fig. '1, and to convey the butter from the plate 69 to the ployed. The carrier 70 com rises a lower plate 71 that is arranged to side under the plate 69, and a pair of vertical side members 72, that are connected by a top bar or strip extended arms 75 that are rigidly secured to bars 76 adapted to guides 77 that are secured to the inclined frame member 68,-and

said bars 76 are reciprocated endwise once for each cube of butter to be wrapped, the

butter being received from'the plate 69 and ass ss into the pocket 56:

sai roller. I The inclined frame 86 is provided with In order to remove. the butter from the plate 69in case there is a tendency of the butter to cling to the plate, the carrier is provided with a pair of side wings 78 having vertically disposed pivot pintles 79 in the frame of the carrier, and extending from the pivot point are arms 80 that are arranged to engage stationary cams 81' carried by the actionof the side walls 78 against the butter cube takes place only at the end of the return'movement of the carrier, and should there be any movement of the butter cube while the side Walls. 78 are gripping it, this movement is so small as to be practically negligible and the gripping action therefore takes place without perceptibly marriug the butter cube. The forward or. lower edge of theplate 71 is provided with arecess 72 in order to expose the lower face of the cube of butter, and after the butter has been slid into the pocket 56, the lower face of the butter will tend to remainwithin the pocket, on a wrapper that is carried into the ocket with the butter, and the carrier will t on be free to return for another cube.

During the movement of the carrier between the conveyer and the pocket 56 the sheet of paper or other wrapping material isplaced below the carrier, and the latter, caraper into the pocket 56, together with the liutter, thus forming the initial fold in the wrap er. In this waythe butter or other artic e to be wrapped-practically constitutes the initial 'foldin means for the wrapper.

In wra pingt e butter any suitable material may e employed, such, for instance, as cheesecloth, wax paper or the like, andthis material is wound in the form of a strip 'on a rying the cube of butter, moves the sheet of carrying shaft or drum 84 ada ted to suit-f able bearings at the top of the strip is fed over the roller 85 at the upper poi'tion'of andnclined stationary frame 86, that is disposed at a right. angle to the plane of movement of the carrier 70. At the u portion of this frame is a guard 87 WElChturns the end of the stri downward after it ame. This passes from the roller 8 and a spring-88is preferably. employed to engage the top of the strip immediately over the' roller, in order'to 1 prevent the weig 't of themain portion of the stri from drawing the end thereofback over frame 86 is a horzzonta ly disposed cutter plate 102, and said frame carries guides 103,

snitahie guides for a pair of iongitudinall movable bars 90 that are connected at their upper and lower ends by cross bars 91 and 92. The upper bar 91 carries a fixed jaw 93, which passes under the end of the strip of wrap ing material when .the gripper is raise to'the position shown in Fig. 5, The cross bar 9] is further rovided with pivoted lugs for the support 0 a'sinall shaft 94, carupward, and in so doing will rock the shaft 94 and move the gripping jaw 95 away from the gripping -aw 93, the open jaws being moved upward until the reach the guard 87, and the partsassume the position shown in Fig. 5. The rod 98 is then moved downward and as a result of this, the shaft 94 is first tasked, and the movable gripper 95 is forced into contact with the wrapping strip, the, latter hein firmly held between the two jaws, and hi6 as downward movement of the rod 98 is continued, the jaws are-moved down to pull the end of the wrapping-strip across the p eth of inoverncntof the carrier 70-.

Secured to the upper ortion of the fixed or a removable cutter plate 104,- these plates opening to the positions shown in Figs.

5 and 7 to permit the passage ofthe wrapper gripping jaws. The movable outta: plate 104 is provided with arms 105 that are connected by links 106 to the upper portion of the movable carrier 70, so that as said carrier moves downward toward the box.56, the cutter-104 will he moved in the direction of the stationery cutter 102, and the strip of wrapping material will be severed in order to form a sheet of proper sizefor the wrapping of the cube of butter. or other material. At the same time, that is to sa during the movement of the carrier in the direction of the )uckct 56, the rod 98 will start its up ward movement, and the shaft 94 will be rocked drawing the jaw 95 downward and releasing thelower end ofthe apcr, and this releasing movement at the Eottom of the strip and the cutting operation, occur only after the forward end of the carrier or the forward edge of the cube of butter or other material has already engaged with the wrap ing strip, and there will be no danger of the s eet thus severed falling from position. The sheet is carried into the pocket or wrapping b02156, and is folded into U shape form, thus embracing three sides of the cube of butter .fold

or other material, and receiving the initial disk 52. Durin the rotative movement of the pockets an their carrying disks, this anti-friction roller will travel first from the point a of the cam 51 to the point b, and; will move the foldingplate 58 overthe'topjof the pocket, folding o :the projecting ortion of the wrap er, and then, durin movement of the ockets and their carrying disks,-the roller W1 travel toward the point e of the cam, and in so doing the plate 58 will be withdrawn, as shown to the left of Fig. 1.

The late 59 is ivoted to one arm of a bell crank ever 113 t at is-mounted at one'e'nd of. a cross bar 111, and the opposite end of said bell crank lever is provided with an antifriction roller 114 that is arranged to travel in the cam groove 55 on the stationary cam disk 53.

' ther During the first step of the pockets I and their'can'ying'disks from the receiving position, the roller 114 will travel in .a path concentric with the disk until it reaches the point (1 of the cam, see Fig. 1, and during the next step, from oin't d' to point-e,, the roller will be actuated for the purpose. of moving the plate 59 over the open part of the pocket and folding down the second side of the wrapper, and said plate will remain in this position durin the tucking and folding of the ends of the .wrap )er, until the roller reachesthe point of t scam, and between the point and t e pointy of the cam, the roller will e moved outward, and the folding plate 59 will be withdrawn, leaving the pocket open, so that the completely wrap ed cube of butter nay fall on to a traveling elt 115 ar'ran ed at the lower portion of the Inachine, and receiving motion through a suit;- able belt connecting 1 16 from the main shaft; (see Fig. 4). The pocket remains 0 on until it has again moved to. a position in a 'neme'nt with the, butter feeding carrier 70..

p The mechanism for folding the ends of the Wrap er is shown at the left of Fig. 1, and in deta' in Figs. 9 to 13, inclusive. Atthe opposite sides of the frame are arranged bearings or s11 ports 117 for the reception of a pair of sli ably mounted rods 118 that are rigidly secured ton transversely extending bar 119. The centralportion of this bar is circular in-cross sectionandis received with cross plate: :Eromjthe. ends lanes in Fig. 9
